Valorization between Early Atlases and Island Books: October at the Biblioteca Correr, Venice. The conceptual links between two atlas projects, those of Joan Blaeu (1598/99-1673), active as cartographer in Amsterdam and official mapmaker to the Dutch East India Company (1638-73), and Vincenzo Maria Coronelli (1650-1718), Franciscan Friar and official cosmographer to the Republic of Venice, have formed a recurring and stimulating thread throughout the month I spent in Venice as an intern at the library of the Museo Correr.
